Firewalls

Firewalls are an essential part of any efforts to improve the security of the data on your network, PC or laptop. Personal firewalls are generally software applications which ‘filter’ traffic entering or leaving a single computer.

Hardware firewalls are dedicated devices use primarily in professional organizations on local networks to protect confidential corporate and client information.

What is a network firewall?
A firewall is a bit like a gatekeeper or a first class personal assistant – it blocks unwanted or unwelcome traffic, while on the other hand allowing important information to flow freely. As firewalls need configuring, it is important that you identify what ‘policies’ you want to adopt to differentiate between incoming and outgoing traffic.

Why a firewall?

The internet is a society like any other, and is plagued with all kinds of anti-social behaviour – the digital equivalent of graffiti, tampering with letters, junk mail or playing loud music. A firewall generally tries to keep these behaviours out of the way while work can be done efficiently and effectively.

Some companies have policies on how data is stored and used, therefore protection is essential to ensure that these policies are adhered to. If data about individuals is stored then legislation requires that data to be properly managed and that adequate protection is taken.

Many of the reasons why individuals and companies do not embrace networks is the fear of security. Firewalls offer a high degree of reassurance not only to an organisation but also to its customers and clients.
